The Root of Thought: What Do Glial Cells Do? He thought this would confirm Pedro's theory that glial cells were insulators. What he found instead was that the electrical potential of glial cells responded to potassium. Kuffler and colleagues found that astrocytes exhibited an electrical potential, much like neurons.

Power steering control valve It puts a small amount of liquid under pressure using a pump, which is powered by the engine. When the wheels turn, the power steering control valve (PSCV) directs the flow of the power steering fluid to the proper end of the power cylinder, which results in smoother and safer vehicle handling. However, like all auto parts, your PSCV can eventually wear out and malfunction, resulting in unreliable steering.
